“It is no help in understanding either why “good” is indefinable, or how it is used, to explain that a good action is one which corresponds to the Form of the Good, or to the Moral Law. It is equally pointless to be told that true statements correspond to the way the world is. The appropriate position for the “antirealist” is just to admit that nothing will explicate “theory-independent truth,” just as nothing will explicate “noninstrumental goodness” or “nonfunctional beauty,” and to move the burden of proof back [to the realist by asking] “What would we lose if we had no ahistorical theory-independent notion of truth?””
